Don't ever accept a provider's bill or invoice at face value. Did you communicate with your insurance carrier? Their major function is to negotiate those billed charges down to something reasonable. My provider billed $411 for the same CPT. My insurance slashed it by 50%. My copay was $40. No deductible applied, due to the plan's provision for a PCP visit. You'll need to ensure that your insurance did their job and issued an EOB. Once the insurance has ruled on it, then you can proceed to negotiate with your provider. If the provider directly sent you a balance bill and you've not heard from your insurance carrier, then you need to reach out to insurance, not your creditors. The creditor will also have avenues you may pursue, such as financial assistance or self-pay plans. Some may not be available due to your insurance coverage. Some people fly without a parachute and rely on the self-pay. You'd be surprised how zero-sum that can be. Most notices demanding payment are subtly deceptive, even from legitimate creditors. I always rely on the online billing portal, or a human being who can pull up my account over the phone. Always get the latest statement. Compare all the paperwork, because timing and wording always matter a lot, especially when they're wrong!
